UV fluorescent inks are made by adding corresponding visible fluorescent compounds to the ink. Its anti-counterfeiting features are: the printed matter is invisible under ordinary light, and can emit glittering fluorescence under ultraviolet light. There are invisible and visible UV fluorescent inks. The special ink that emits visible light (400-800nm) is excited by ultraviolet light (200-400nm), which is called ultraviolet fluorescent ink. According to different excitation wavelengths, it is divided into short-wave and long-wave. The excitation wavelength of 254nm is called short-wave ultraviolet fluorescent ink, and the excitation wavelength of 365nm is called long-wave ultraviolet fluorescent ink. Blue and other colors; colored can make the original color shine; discoloration can make one color into another color.

UVLED coating glazing has the characteristics of fast curing, low-temperature curing, safety and environmental protection, and excellent film-forming performance, which helps to solve many problems in the gloss processing process of printed products and fills many shortcomings of traditional glazing.

UV ink is also called ultraviolet curing ink, which uses a certain wavelength of ultraviolet radiation to turn liquid UV ink into solid ink through an instant photochemical reaction.

UV offset printing ink is a high-viscosity slurry fluid. The resins used in the production of offset printing ink binders mainly include rosin-modified phenolic resin, alkyd resin, and petroleum resin.

Specialty paper is paper with a special purpose and a relatively small output. There are many types of specialty papers, which are collectively referred to as various special-purpose papers or art papers. Now sellers collectively refer to art papers such as embossed paper as specialty papers, mainly to simplify the confusion of terms caused by the wide variety.
